So yesterday my son and I were putting hardware cloth over the ventilation at the top of the coop. We have new "replacement" chicks coming in a few days (to replace the ones that jumped out of the box at the post office) and we needed to get the two month old "teenagers" in the big coop - even if the coop isn't done yet. We wanted to make sure it was very "predator proof" first.
But some Carolina Wrens (our state bird, lol) have made a nest in the coop and have three hungry babies inside. We had a system going. We would hammer until we saw mama or daddy bird (or both, they mate for life and both feed the babies) fly to the top of the coop. We would stop hammering, they would come in and feed their brood while we stood there, then they would fly away and we would hammer again. This went on for a couple of hours and it was really neat to get to be so close to a nest of babies being fed.
Anyway, now I'm in a quandary. If I close up the ventilation holes, the parents won't be able to get back to their nest of babies, which means the babies will die. If I don't close it up, I risk predators (we live in the country near the woods and have plenty) killing my own babies....
